A kind of treadmill
Technical field
The utility model relates to a kind of treadmill, belongs to the body-building apparatus field.
Background technology
Along with the progressively raising of people's living standard, people also promote gradually to the demand of body-building.Various sanitation park or squares are increasing, and various multigyms emerge in succession.The operation principle of existing treadmill is: after the people sets foot on transport tape opening switch, transport tape moves backward under the effect of drive motors.
But, traditional treadmill is not installed anti-tipping apparatus, its artificial or other unexpectedly still work on while toppling over, treadmill can't stop automatically, and transport tape also still can move backward fast under the effect of drive motors, very likely the people is caused to further injury, the power supply of its connection simultaneously also easily causes extra accident, as floods, get an electric shock, hurt sb.'s feelings etc., security is low.
Therefore, the continuation of treadmill is used in a large number, must consider its security performance is made a search more.
Summary of the invention
Main purpose of the present utility model is to provide a kind of treadmill, its out-put supply can be disconnected when described treadmill is toppled over or tilted to certain angle, thereby it is quit work, and avoids unexpected and occurs.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of treadmill, comprise body and be arranged on the drive motors on body, also comprise control system and be arranged on the anti-dumping switch on the body base, described anti-dumping switch is connected to the input of control system, and the output of control system is connected to drive motors.
Preferably, described anti-dumping switch comprises main body, and the lower end of main body is provided with installing hole, and the left and right sides of main body is provided with the emission base and receives base, wherein in main body, is provided with gravity sensor; Gravity sensor is to calculate three direction of principal axis and output angle data judges, can recognize that the angle of toppling over is large, is subject to external interference little.
The beneficial effects of the utility model are: the utility model can guarantee when electrical equipment is toppled over or tilt to certain angle, its out-put supply to be disconnected, thereby it is quit work, and avoids unexpected and occurs.Its design science is reasonable, and cost of manufacture is lower, safe and reliable.
The utility model anti-dumping switch adopts gravity sensor, but high angle and multi-angle identification range of collapse are not subject to the extraneous factor interference such as vibrations, and reliability is high, and volume is little, is convenient to install.
The accompanying drawing explanation
Fig. 1 is the utility model example structure module frame chart.
Fig. 2 is anti-dumping switch structural representation in Fig. 1.
In Fig. 2, mark is described as follows: the 1-main body, and the 2-installing hole, 3-launches base, and 4-receives base, 5-gravity sensor.
The specific embodiment
The realization of the utility model purpose, functional characteristics and beneficial effect, be described further below in conjunction with specific embodiment and accompanying drawing.
Below in conjunction with the drawings and specific embodiments, technical scheme described in the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
Fig. 1 is the utility model example structure module frame chart.As shown in Figure 1, the utility model embodiment treadmill comprises body and is arranged on the drive motors on body, also comprise control system and anti-dumping switch, described anti-dumping switch is connected to the input of control system, and the output of control system is connected to drive motors.
As shown in Figure 2, the utility model embodiment anti-dumping switch, comprise main body 1, and the lower end of main body 1 is provided with installing hole 2, and the left and right sides of main body 1 is provided with emission base 3 and receives base 4, is provided with gravity sensor 5 in main body 1.Gravity sensor 5 is to calculate three direction of principal axis and output angle data judges, can recognize that the angle of toppling over is large, is subject to external interference little.
The utility model embodiment anti-dumping switch adopts gravity sensor 5, but high angle and multi-angle identification range of collapse are not subject to the extraneous factor interference such as vibrations, and reliability is high, and volume is little, is convenient to install.
